Outline of Final Research Achievements

Fiber-optic grating devices have been used as filters for optical communication, mode converters, or fiber-optic sensors. Here, fabrication of long-period fiber-gratings without using an expensive and bulky excimer laser was studied. A low-pressure mercury lamp at 254 nm was used as a writing source. The exposure time was shortened to a one-third of the initial value by improving hydrogen loading. The fabricated long-period gratings were used as temperature and strain sensors. Also, when higher-order propagating modes were excited by off-axis coupling, it was confirmed that the transmission spectrum of the long-period grating was different from that of the fundamental-mode excitation. A vertical-cavity surface-emitting laser was found to be effective as a light source for sensing.
As for another fiber-grating device, a thermally poled fiber for the second-harmonic generation was studied, and quasi phase-matching was performed with periodic exposure with a low-pressure mercury lamp.
